I'm sorry. I know that hawks can be awful. I'm glad your bird is safe!
https://www.fws.gov/forms/3-200-13.pdfThis is what you need to kill one. In To have it considered you have to include info on;
"What hazing or harassment techniques (e.g., horns, pyrotechnics, propane cannons) have you used to manage or eliminate the problem? Of these tools, how often and how long did you use these deterrents (e.g., number of weeks, months, year(s))?
What habitat management measures (e.g., vegetative barriers, longer grass management, fencing and netting) have you used to discourage depredation by birds?
What cultural practices (e.g., crop selection, crop placement, animal and pet management, feeding schedules, and no-bird-feeding policies) have you established to discourage depredation in the areas you have identified? "
AND
"A depredation permit is not considered a long-term solution for most situations. What long-term measures do you plan to take to eliminate or significantly reduce the continued need for killing or removal of birds, or destroying eggs/nests? Discussing how you will continue to use the non-lethal deterrents described in question 5 above can help with answering this question. (Recall that no permit is needed to remove nests without eggs, except for eagles and endangered birds.) "
It's something to consider seriously. This DOES however mean that you can harass or haze hawks away from your property using most non lethal methods. It also means that the covered area is probably an idea you'd want to pursue even if you also wanted to pursue a permit.
Wanted to say this too after reading the post. Even if it's in the act of attacking your birds shooting one is a federal crime with jail time and up to 50K fines. State law can't override this.It's illegal to shoot the hawk without a permit.
